Phylogenetic analyses of the genus Oxyrhynchus and close relatives in the New World subtribe Phaseolinae have established that Vigna populnea is a species of Oxyrhynchus. Thus, a new combination is proposed. The genus Oxyrhynchus now includes O. populneus and two other neotropical species as well as one from the Papuasian region. The nomenclatural history of O. populneus is briefly presented and a comprehensive morphological description of the species is provided. A key to the four species of Oxyrhynchus is included.
